[9] Review request for 8136918: Ensemble uses deprecated flv (vp6) media files hosted on OTN

[Alexander Matveev]

Hi Kevin,

Please review the following:
https://bugs.openjdk.java.net/browse/JDK-8136918
Updated Ensemble and HelloMedia to use oow2010-2.mp4 instead of 
oow2010-2.flv.

Thanks,
Alexander
